Sometime, I get this after booting, before entering Windows.

What does 0xF7BED528 parameter signify? I search Google and find result for 0x0000007B. But I cannot find something for parameter 0xF7BED528. What is this? Why it appears? What is it causing?

Have you installed any other OS's recently or used somthing that may modify the boot sector (TruCrypt, some DRM systems, ect...)? –  Scott Chamberlain Apr 28 '13 at 6:03
    
No.. but I do change hard disk and RAM sometime a year ago. I only notice this problem in recent months. –  Dipa Apr 28 '13 at 7:08

0xF7BED528 is the first parameter. You get the 0x0000007B STOP code with the important parameter 2 with 0xc0000034 which means device not found.

C:\Users\André>err 0xc0000034
# for hex 0xc0000034 / decimal -1073741772
  STATUS_OBJECT_NAME_NOT_FOUND                                   ntstatus.h
# Object Name not found.
# as an HRESULT: Severity: FAILURE (1), FACILITY_NULL (0x0), Code 0x34
# for hex 0x34 / decimal 52
  ERROR_DUP_NAME                                                 winerror.h
# You were not connected because a duplicate name exists on
# the network. If joining a domain, go to System in Control
# Panel to change the computer name and try again. If joining
# a workgroup, choose another workgroup name.
# 2 matches found for "0xc0000034"

This is caused when you change the SATA mode from IDE to AHCI without enabling the AHCI driver first.

Error message occurs after you change the SATA mode of the boot drive

What is the err program that you used in your question? That is interesting. –  Alvin Wong Apr 28 '13 at 7:04
    
So 0xF7BED528 means it happens because the SATA mode is changed? –  Dipa Apr 28 '13 at 7:09
    
@AlvinWong this program is part of the Windows 7 SDK. –  magicandre1981 Apr 28 '13 at 11:01
    
@Dipa no, again you get the 0x0000007B bugcheck. –  magicandre1981 Apr 28 '13 at 11:02
    
I am sorry, I am still confused... I know about 0x0000007B, but what is 0xF7BED528? –  Dipa Apr 29 '13 at 15:53
